Subject: [PATCH] [FIX] use contrib getopt() only on Windows

Otherwise, contrib getopt will clash with the one from the libc when
building statically.

lib64/libc.a(getopt.os):(.data+0x8): multiple definition of `optind'
CMakeFiles/demo_mn_console.dir/__/__/contrib/getopt/getopt.c.o:(.data+0x8): first defined here
lib64/libc.a(getopt.os):(.data+0x4): multiple definition of `opterr'
CMakeFiles/demo_mn_console.dir/__/__/contrib/getopt/getopt.c.o:(.data+0xc): first defined here
/lib64/libc.a(getopt.os): In function `__GI_getopt':
getopt.c:(.text+0x76e): multiple definition of `getopt'
